PDI source type can be DDR, OCM, QSPI flash etc.. But driver allocates memory always from DDR, Since driver supports only DDR source type. Signed-off-by: Appana Durga Kedareswara rao Signed-off-by: Nava kishore Manne --- Changes for v2: -Updated the Fpga Mgr registrations call's to 5.11 -Fixed some minor coding issues as suggested by Moritz. Changes for v3: -Rewritten the Versal fpga Kconfig contents. Changes for v4: -Rebased the changes on linux-next. No functional changes.
